MAGAZINE-'GUN.

SPECIFICATION forming part of Letters Patent No. 313,213, dated March 3, 1885.

(No model.)

To all whom it may concern.-

Be it known that I, JOHN C. KELToN, of the city and county of San Francisco and State of California, have invented an Improvement in Breech-Loading and Magazine Fire-Arms; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to certain improvements in breech-loading and magazine firearms; and it consists of agun having a hinged swinging breech-block with a hinge at the up per front portion, so that the block is thrown 'top view of the same.

upward and-forward when thebreech is opened, and, in connection therewith, of a tubular firing-pin contained within the breech-block, a spring within said firing-pin, by which it may be forced forward, so that its point will strike and explode the cartridge within the barrel, a means for withdrawing this firing-pin, and at the same time compressing the spring when the breech-block is thrown open, a scar and mechanism for holding the pin after the breechblock is closed, and a mechanism connected with the trigger, so that the spring may be released to act upon the firing-pin by pulling the trigger.

My invention further consists in the application of a magazine in the form of a segment of a cylinder extending around beneath the breech-block chamber, and having a hinged door opposite one side of the chamber, through which the cartridges may be dropped into the chamber when the breech-block is open.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure l is a front view of the sear. Fig. 2 is a side view of the sear. Fig. 3 is a bottom view of the sear. Fig. 4 is a rear View of the tubular firing-pin and transverse bar. Fig. 5 is a side view of the pin. Fig. 6 is a Fig. 7 is a longitudinal vertical section of the breech movement closed. Fig. 8 is a side view of the breech movement open. Fig. 9, Sheet 2, isa perspective view showing the rifle with the breechblock opened and the magazine in place.

A is a receiver at the rear of the barrel of the gun, within which the breech-block B works. This breech-block is hinged at the top of its front end to the rear portion of the barrel, so that it may be thrown upward and forward when opened, and when closed it lies within the receiver and is held by a cam-latch, h, a thumb-piece, h, projecting to one side, and connected with the same shaft as the camlatch, so that the breechblock may be thrown open by pressing upward upon the thumbpiece, in the manner of the present Springfield rifie.

In my invention I have shown a projection or lug, H, beneath which the edge of the thumb-piece may be pressed by a slight movement after the breech-block is closed, and insure it from being thrown open by the explosion of the cartridge. The breech-bl0ck B is made hollow, and within it is a hollow cylindrical firing-pin, 0, having a projecting point, C, which may extend through a corresponding hole in the front end of the breech-block, so as to strike against the cartridge or primer and explode it when the firing-pin is projected forward by the action of the spring. The mainspring D is contained within the hollow firing-pin 0, its front end pressing against the front interior of the firing-pin, while its rear end presses against the inclined sloping shoulder E of the sear E. This sear E is pivoted below its center upon the pivotscrew 6, which is fixed from side to side of the breech-block, passing through the slot 0 in the rear portion of the firing-pin, as shown, this method of pivoting, together with the action of the rear end of the nlainspring against the sloping shoulder E, causing the necessary movement to engage the sear-nosing e c with the notches c c in the lower portion of the slot 0 at the rear of the firing-pin when the spring has been compressed. The lug 6 projects from the sear downward through a slot, b, in the breech-block.

G G are arms having projections at right angles with them at the front end, through which a pin passes to pivot them to the rear portion of the barrel and out of line with the hinge-pin of the breech-block, as shown at G. The rear of the arms G have slots made in them, and the transverse bar 0 has its ends projecting far enough to enter the slots in the bars G. When the breech-block is opened, moving about its pivot-pin in front, the arms G are turned up along with it, and as they have the center about which they move out of line with the center of motion of the breechblock 13 it will be seen that the slot 9 at the ends of the arms will act upon the proiecting arm and press it backward, thus wit.idrawing the firing-pin and compressing the spring D against sear E. This action causes the searnoses e e to engage notches c in the firing-pin, and thus hold the firing-pin back while the breech-block is being closed. The cartridges are contained in a segment ofa cylinder, I,

which extends around beneath the receiver A, within which the breech-block closes, and this holder is of a length suificient to receive the cartridge, and the distance between its inner and outer sides is sufficient for the diameter of the cartridge.

The cartridge-follower i is acted upon by springs or other mechanical contrivances, so as to cause it to press the cartridges sidewise and force them to travel around in the annular-chamber which the casing I forms beneath the receiver A. z" is a hinged lid or door at the left side of the cartridge case or holder. This side extends up high enough to allow the lid to swing inward above the receiver A when the breech-bloek B has been thrown open. While the breech-block is open thelid i may be operated by the thumb of the right hand, or by a fixed spring, and the cartridge will be dropped into the receiver, when it can be pushed in the chamber of the gun by forward movement of the thumb. \Vhen the breechblock is closed, it acts to closethe lid 1' of the cartridge case or receiver, and allows another cartridge to be brought into position ready to drop into the receiver A when the breechblock is again opened. WVhen the breech-block is closed, the cam-latch h falls into the concavity provided for it at the rear of the receiver A,and the thumb-piece h may be pressed laterally, so as to engage with the safety-notch H,to prevent the breech-block flying open, as before described.

F is the trigger of the gun. F is a bar or link extending from this trigger forward, having its front end attached to the lower end of the ejector-stud], which is pivoted below the receiver A, and its point extending upward, as shown. When the trigger is pulled, it acts through therod Fand the ejector-stud), causing it to oscillate upon its pivot, so that the upper part of the stud moves backward and acts upon the lug e of the sear E, and this disengages the ends 0 of the sear from the notch c, and allows the firing-pin Gto be forced forward by the mainspring D, so that its point C will strike and explode the cartridge. If it is desired,the magazine may be detached and the gun will operate as a single breech-loader.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-

1. In a gun, the receiver A, hinged swinging breech-block B, with arms pivoted upon each side and eccentrically to the pivot of the breech-block, together with the firingpin sliding within the breech-block containing a mainspring, and having a transverse bar, 0', the endsof which engage slots in the arms G, so that the.firing-pin may be retracted and the spring compressed by the opening of the breech-block, as herein described.

2. In a gun, the receiver A, hinged swinging breech-block B, the tubular firing-pin con tained within the breech-block, and itselfcontaining the mainspring, with a means for retracting the firing-pin and compressing the niainspring,together with the sear E, pivoted below its center,and having sear-noses e,adapted to engage notches 0 in the slotted rear end of the firing-pin, as herein described.

3. In a gun, the receiver A, hinged swing ing breech-block B, with its contained hollow firing-pin, and mainspring contained within the breechblock,and the sear E, pivoted and having noses or catches, as shown, together with the ejector-stud f, connected with the trigger F, substantially as herein described.

4. The receiver A, swinging breech-block, with the arms G turning upon different centers, the contained firing-pin, mainspring,and holding mechanism within the breech-block, in combination with the cam-latch located within the rear end of the breech-block, to hold the same within the receiver, a thumb-piece, h, and safety-notch H,substantia-l]y as described.

5. In a gun, the receiver A, hinged swinging breech-block B, with its contained firingpin, spring, and actuating mechanism within the breechblock, and the arms G, in combination with the segmental magazine I, extending beneath the receiver, and the lid i, substantially as herein described.

In witness whereof I have hereunto set my hand. F
